This invention relates to wireless communication systems, specifically improving synchronization and paging signal reception for user equipment (UE) in environments with beamforming. The problem addressed is ensuring reliable reception of synchronization signal blocks (SSBs) and paging signals when transmitted using different antenna port configurations, which can lead to misalignment in beamforming at the UE. The method involves transmitting an SSB to a UE using a first antenna port configuration and transmitting a paging signal to the same UE using a second antenna port configuration. The SSB and the demodulation reference signal (DMRS) of the paging signal are quasi co-located (QCL) with respect to receive beamforming at the UE, meaning the UE can use the same beamforming parameters for both signals. Additionally, the antenna ports of the first configuration are quasi co-located with those of the second configuration, ensuring spatial consistency between the SSB and paging signal transmissions. This alignment allows the UE to efficiently track and receive both signals without requiring separate beamforming adjustments, improving reliability and reducing overhead in wireless communication systems.
2. The method of claim 1 , wherein: the paging signal comprises at least one of a paging message, a paging schedule, or a paging indication.
A method for wireless communication involves transmitting a paging signal to a user device in a wireless network.

The problem addressed is ensuring efficient and reliable reception of paging signals by aligning the receive beamforming configuration with the transmission characteristics of the SSB and paging signal. The apparatus includes a processor and memory storing instructions to receive an indication of two antenna port configurations: one for transmitting an SSB and another for transmitting a paging signal. The SSB antenna ports are quasi co-located with the paging signal antenna ports, meaning they share certain channel properties like spatial parameters. The apparatus determines a receive antenna port configuration for the paging signal based on this indication. It then receives the SSB and the paging signal from a base station, ensuring that the SSB and the demodulation reference signal (DMRS) of the paging signal are quasi co-located with respect to the UE's receive beamforming. This alignment optimizes signal reception by maintaining consistent spatial characteristics between the SSB and paging signal, reducing the need for frequent beam adjustments and improving energy efficiency. The invention enhances paging signal reliability in wireless networks, particularly in scenarios with dynamic beamforming.
27. A method for wireless communication, comprising: time-division multiplexing a synchronization signal block (SSB) and a paging signal; transmitting the SSB to a user equipment (UE) in a different slot than the paging signal; and transmitting a paging signal to the UE, wherein the SSB and a demodulation reference signal (DMRS) of the paging signal are quasi co-located with respect to receive beamforming at the UE.
This invention relates to wireless communication systems, specifically improving synchronization and paging efficiency in cellular networks. The problem addressed is the need to optimize the transmission of synchronization signals and paging messages to user equipment (UE) while maintaining reliable beamforming performance. Traditional systems often transmit synchronization signal blocks (SSBs) and paging signals in separate time slots, which can lead to inefficiencies in resource allocation and beamforming accuracy. The method involves time-division multiplexing an SSB and a paging signal, transmitting them in different slots to avoid interference. The SSB provides timing and frequency synchronization, while the paging signal alerts the UE of incoming data. A key innovation is that the SSB and the demodulation reference signal (DMRS) of the paging signal are quasi co-located (QCL) with respect to receive beamforming at the UE. This means the UE can use the same beamforming parameters for both signals, improving reception quality and reducing complexity. The QCL relationship ensures that the UE can accurately track and decode the paging signal based on the beamforming characteristics of the SSB, enhancing reliability in dynamic wireless environments. This approach optimizes resource usage and improves synchronization and paging efficiency in wireless networks.

This invention relates to wireless communication systems, specifically improving synchronization and paging signal transmission efficiency. The problem addressed is the need to optimize resource allocation and beamforming for synchronization signal blocks (SSBs) and paging signals in wireless networks, particularly in scenarios where beamforming alignment between these signals is critical for reliable communication. The apparatus includes a processor and memory storing instructions that, when executed, enable time-division multiplexing of an SSB and a paging signal. The SSB and paging signal are transmitted in different time slots to avoid interference and improve resource utilization. Additionally, the SSB and the demodulation reference signal (DMRS) of the paging signal are quasi co-located (QCL) with respect to receive beamforming at the user equipment (UE). This QCL relationship ensures that the UE can use the same beamforming configuration for both signals, reducing complexity and improving reception reliability.

29. A method for wireless communication, comprising: receiving a synchronization signal block (SSB) from a base station; and receiving a paging signal from the base station, wherein the SSB is received in a different slot than the paging signal, and the SSB and a demodulation reference signal (DMRS) of the paging signal are quasi co-located with respect to receive beamforming at a user equipment.
This invention relates to wireless communication systems, specifically improving synchronization and paging signal reception in user equipment (UE). The problem addressed is ensuring reliable reception of paging signals while optimizing beamforming efficiency. In wireless networks, UEs must synchronize with the base station using synchronization signal blocks (SSBs) and monitor paging signals for incoming data. However, traditional methods may suffer from beamforming mismatches between SSBs and paging signals, leading to reception errors. The invention describes a method where a UE receives an SSB from a base station in one time slot and a paging signal in a different slot. The SSB and the demodulation reference signal (DMRS) of the paging signal are quasi co-located (QCL), meaning they share certain channel properties, such as Doppler shift and delay spread. This QCL relationship allows the UE to apply the same receive beamforming parameters used for the SSB to the DMRS of the paging signal, improving reception accuracy. The DMRS is a reference signal used for demodulating the paging signal, and its QCL with the SSB ensures consistent beamforming. This approach reduces the need for separate beamforming adjustments, enhancing efficiency and reliability in wireless communication.

This invention relates to wireless communication systems, specifically improving synchronization and paging signal reception in user equipment (UE). The problem addressed is efficient beamforming for receiving synchronization signals and paging signals, which are typically transmitted in different time slots but may require similar beamforming characteristics. The apparatus includes a processor, memory, and instructions to receive a synchronization signal block (SSB) and a paging signal from a base station. The SSB and the demodulation reference signal (DMRS) of the paging signal are quasi co-located (QCL), meaning they share certain channel properties such as Doppler shift, delay spread, and spatial parameters. This QCL relationship allows the UE to use the same receive beamforming configuration for both signals, even though they are transmitted in different slots. By leveraging this QCL assumption, the UE can reduce the complexity and overhead of beamforming adjustments, improving power efficiency and reliability in wireless communication.
